Ashley D Walters is as always solid as an actor, starting his career as one of the members of the infamous grime-group So Solid Crew he quickly became a force to be reckoned with in UK film and TV-scene and even some stints in American movies like for instance 'Get Rich Or Die Trying' with 50 Cent.
This movie is sort of reminiscent of 'Get Rich Or Die Trying' but it's more playful and the characters aren't any wannabe-gangsters or gangsters (at least not Asher D and his friends)... I'd probably compare it more to Ernest Dickerson's 'Juice'.
Surprisingly despite this movie being about a rap-group in London, Asher D doesn't rap once in the movie, he plays the DJ and producer of the group.
The other actors portraying the rest of the group are skillful on the mic tho, so it doesn't suffer from it and Christopher Steward who plays Fable is genuinely likable and shows good range in acting as well as rapping.
The movie does have some flaws tho, the "Romeo and Juliet" aspect of the movie doesn't really get all to captivating for the viewer, I don't know where the problem lies exactly but I found myself not caring too much whether the 2 would stay together or not.
But overall the story keeps you entertained and visually the movie makes London look really good, even in the "less good" areas it's visually pleasing.
Comparing it to other movies of the same kind it's not up there with Kidulthood and Adulthood but it's miles beyond Rollin With The 9's and even slightly better than Bullet Boy IMO.
